Power Unit Energy Cost at 58% average load factor: a worked example

Suppose average load factor falls to 58%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Calculate power unit energy cost for hydraulic, pneumatic & fluid power systems planning, quoting, troubleshooting, capacity review, or process improvement.

The inputs for this scenario

  • Power unit operating hours: 100 units (held at the documented default)
  • Energy cost per operating hour: 45 $ / unit (held at the documented default)
  • Average load (duty) factor: 58 % (the input this scenario stresses; the baseline uses 80)
  • Fixed standby and cooling cost: 250 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Power Unit Energy Cost cost = quantity × rate × capture factor + fixed cost.
  • Weighted cost works out to 2,860 $ at these inputs, and this is the headline figure for the scenario.
  • Per piece value works out to 28.6 $ / piece at these inputs.
  • Captured value works out to 2,610 $ at these inputs.
  • Fixed adjustment works out to 250 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where average load factor sits at 80% and the headline result is 3,850 $, this scenario comes in 25.71% below the baseline at 2,860 $.
  • It computes the total energy cost of running a power unit — hours times hourly cost times load factor plus fixed standby cost — and the cost per operating hour. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.

Results at a glance

  • Weighted cost: 2,860 $ (headline result)
  • Per piece value: 28.6 $ / piece
  • Captured value: 2,610 $
  • Fixed adjustment: 250 $
